Abstract:   (1268 Views)
We consider a cooperative spectrum sharing non-orthogonal multiple access (NOMA) network, where a
secondary transmitter assists transmission from a primary transmitter to a primary receiver with poor channel
conditions, and at the same time transmits to a secondary receiver with strong channel conditions. The secondary
transmitter is assumed to be energy-constrained and powered by an energy access point located in its vicinity. In order
to cancel the self-interference at the full-duplex multi-antenna secondary transmitter, two zero-forcing (ZF)-based
beamforming schemes and a maximum ratio combining/maximum ratio transmission scheme are designed and the
corresponding outage probability analysis of the primary and secondary networks, are derived. Outage probability
results are used to study the delay-constrained throughput of the system. Our results suggest that by using ZF-based
beamforming schemes depending on the number of transmit/receive antennas at the full-duplex secondary transmitter
significant performance improvement can be achieved compared to the half-duplex counterpart. Moreover, our results
indicate that proposed ZF-based schemes achieves a zero-diversity order.
